To read values from port of microcontroller?

[Pari Boopathy]

I am connecting my IR receiver(Output to VCC and Ground to 7th pin of Port-C) to TM4C123GH6PM Microcontroller.
Whenever i press the button in TV remote,,the IR Receiver which receives the data using Pulse Length Technique..In coding i read the values using this command and store it in array..using CCS Compiler.
c=GPIOPinRead(GPIO_PORTC_BASE,GPIO_INT_PIN_7);

Is this command is enough to read the values from IR receiver?Whether it stores 12-bit(Command-7 bit and Address-5 bit) in that array by reading one time? Reply as soon as possible..

IR receiver will have 3 pins usually. VCC, GND, OUT. VCC should be connected to +5V, GND to GND and OUT to MCU input pin.

Thats fine sir..i am asking the coding part??

I don't know about much controller you are using and its API which you used but i assumed you doing coding in c language so its better you use pin in interrupt and stored your ones and zeros separately as shown example code below

    if((zero==1)||(one==1)) // if one or zero received, save it in rec array
     {
         if(zero==1)
         {
             rec[i]=0;
             i++;
             zero=0;
          }
 
          if(one==1)
          {
              rec[i]=1;
              i++;
              one=0;
           }
 
/*****************************************************/
 
          if(i==5) // if i=5, all code received
          {
              x=0;    z=4; i=0;
              for(n=1;n<=5;n++)
              {
                   if(z>25)
                   goto again;
 
                  for(j=x;j<=z;j++) // start checking codes if .......
                  {
                       if(code_x[j]==rec[j-x])
                       {
                            similar++; // if all numbers are equal, similar=5
                            if(similar==5)
                            {
                                 portb=n;
                                 for(m=0;m<=4;m++)
                                 {
                                      rec[m]=0;
                                 }
                                 similar=0; // when the correct code received
                                 goto again;
                             }
                        }
                    }
 
              x+=5;
              z+=5;
              similar=0;
         }
     }
 
}
   again:
   ccp1f=0;   //clear int overflow flag
   set_timer1(0);
   fall=0;
}

u can use this as reference
